Changing attached properties at runtime

Hi all,

I discover the product and I have an ambitous project for my home.

I try to change the attached properties at runtime.

In clear, I want to change the value of Canvas.Top of an element to make move up.

The idea is to have an element bigger than the screen and by using a button move it so the bottom is aligned with the bottom of the screen or the top is aligned with the top.

I first try the scroill viewer but I didn’t find any property allowing to scroll by command.

Maybe oone of you have a solution for me.

Thanks for your help
